I'm looking for a reasonably accurate, compact digital tire gauge that fits easily in glove box and can be read in low light conditions. My eye's ain't what they use to be and I now have trouble reading pencil gauges etc.. Based on lots of good reviews, I bought an Entenwolf 300 on Amazon a year or so ago and it was great for under 10 bucks. It read within 1 psi of my Joe's analog dial gauge and my son's Intercomp digital gauge. I gave it to my SIL who at 75 still religiously checks her tire pressure but has the same problems I do with pencil gauges. Last week I bought two more Entenwolfs (one for each of my cars). I was bummed as both were off quite a bit off compared to my first one. One was about 2.5 and the other 3.5 PSI low when compared to my gauges (and the cars TPMS reading). They both went back to Amazon this morning. Anyone have recommendations for something more or less the same size, reasonably accurate, has a clear digital readout and still relatively inexpensive? As mentioned I have access to better gauges if more accuracy is ever needed.
